I haven't seen the details yet, doesn't the UI scale with these larger screens? I still agree with the premise in the ad but if they have adjusted the UI to work well with one hand then I might consider it.
It's funny watching some people trying to operate some of the larger phones. They're literally tossing it up and down and catching it just to reach the various portions of the screen with one hand.
Ends up looking like the person is masturbating with their phone.
